The Science Behind LED Light Therapy in Reducing Acne
Acne is a common skin condition that affects millions of people around the world. From hormonal imbalances to environmental factors, there are several reasons why acne appears on the skin. While there are several topical treatments and oral medications available to reduce acne, many people are now turning towards LED light therapy to treat acne. In this blog post, we'll explore the science behind LED light therapy and its effectiveness in reducing acne.
First, it's important to understand what LED light therapy is and how it works. LED stands for "light-emitting diode" and it's a type of non-invasive therapy that uses different wavelengths of light to treat various skin conditions. In the case of acne, the blue light (405-420nm) targets the acne-causing bacteria called P. acnes, while the red light (630-660nm) reduces inflammation and promotes skin healing.
Multiple studies have shown the effectiveness of LED light therapy in reducing acne. In one study published in the Journal of Clinical and Aesthetic Dermatology, 30 patients received eight sessions of blue and red light therapy twice a week for four weeks. The researchers found that the total number of acne lesions reduced by 64% compared to the baseline, and 73% of the patients reported improvement in their acne.
Another study published in the Journal of Investigative Dermatology found that blue light therapy works by inducing a chemical called porphyrin in the P. acnes bacteria that destroys them. Additionally, they found that blue light therapy also reduces sebum production, which is the primary cause of acne.
LED light therapy is also a safe and non-invasive treatment compared to other acne treatments that may have side effects. According to a review published in the Journal of Cosmetic and Laser Therapy, LED light therapy does not cause systemic side effects and is well-tolerated by patients with minimal adverse effects.
However, it's important to note that LED light therapy may not work for everyone. Depending on the severity of acne, it may require multiple sessions and maintenance treatments. Additionally, LED light therapy should be used in combination with other acne treatments such as topical creams or oral medications for optimal results.
In conclusion, LED light therapy is an effective and safe treatment option for reducing acne. The blue and red light wavelengths specifically target the acne-causing bacteria and reduce inflammation, respectively. Several studies have shown its effectiveness in reducing acne lesions without causing any significant side effects. However, LED light therapy may not work for everyone and should be used in combination with other treatments. If you're interested in trying LED light therapy for acne, it's best to consult with an esthetician to determine the best treatment plan for your needs.
